down to the oceans

                   down to the oceans

  

This time am going to write about four more oceanic features.

Continental shelf

This a gently sloping area that borders a continent. It extends offshore from almost nothing to 1000 miles wide and about 180 meters deep.

Continental slope

This a very steep slope that drops down from the continental shelf. It could be 12 miles wide and 10000 feet deep.

Abbysal plane 

This is the most level surface of planet Earth. If sediment collects over the rough parts of the ocean floor we call it an abbysal plane.

Mid ocean ridges

these are continuous mountain chains that can be found in every big ocean. They represent more than 20 percent of Earth’s surface.
